Leopard: Painful HD Permission Repairing Procedure

If you tried to repair permissions on your computer after having installed Leopard, you might have already noticed how it is now resource consuming.
Several process are being launched when repairing permissions:
- mds requiring 20% of a 3.0GHZ Xeon
- installdb requiring 97% of a single Xeon core
- then repair_packages requiring 97% of CPU resources!
If on a Quad Core Xeon, such resource-consuming process will be carried out quickly, it might take much more time on a less powerful Mac Intel, and even more on older PPC-based models which might simply be not usable for about one hour!
In addition, if you installed the last update for Apple Remote Desktop Client, you will have an error message indicating that the the SUID file: "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired.
If Apple should quickly correct this problem, the procedure is currently far from being as fast as in previous OS X version, and users should be aware of it before launching it.
